Well, question is: Does a confirmation dialog actually provide better
protection
than an undo function? I've often realized I made a mistake only _after_
clicking that "OK" button on the confirm dialog because I got so used to
those
dialogs that I answer them automatically.

Yes, but isn't that just learned behavior? Would you be scared when moving
a file
to trash without confirmation? Probably not, because you know you can
easily
restore it if you accidentally moved it.
And if we can teach users that they can easily revert accidents, maybe
this can
give them confidence as well.

Data is the point. I'd love to be able to do a usability test with "undo
instead of
confirmation" to see how much this actually scares users. I would not
release this without usability testing of course.
We are generally in a mood of taking bold steps outside of the known in
Plasma Active, so why not trying this as well?
